To make practical use of this system, the powering paths to the receiver devices need to be created automatically. This paper presents a receiver localization method suitable for the 2D WPT system. The feasibility of this method is evaluated by both simulation and experimentation. Moreover, we have implemented a demonstration system that automatically localizes the receiver, establishes the route, and transmits the power.","PeriodicalId":199234,"journal":{"name":"2017 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128254630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to shorten the calculation time, we are developing a simulator using vertical plane launch (VPL) technique which is known as speedy ray searching method. In this paper, we evaluate the calculation accuracy and the calculation time of the VPL. First, we describe the calculation procedure of VPL. Next, we describe the measurement of propagation characteristics in an outdoor environment which size is 200 m × 200 m. We put base station on a roof top, and measure the propagation characteristics along some routes on the ground. We compare the measurements with the estimation result of developed, imaging, and ray-launching methods, and then show that the calculation error of the each method is around 5dB. However, the calculation time of developed method is 1/150 of imaging method and 1/7 of ray-launching method. Therefore capability of radio propagation estimation in extremely short time is realized.","PeriodicalId":199234,"journal":{"name":"2017 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"124 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124650419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A section of design interest in the electromagnetic (EM) model is replaced by ‘n’ pieces cascaded ABCD-Matrixes, and each ABCD-Matrix is the EM-simulated ABCD-parameter of pre-assigned cell circuit (PCC). Finally the optimal exponent parameter of ABCD-Matrix is transferred to original optimization variables. The proposed TSM not only has the advantages of circuit tuning element-less (CTEL) TSM in prior art but also clears the number range limitation that the tuning parameter must be positive for tuning in CTEL TSM. The proposed method has the second minimal specification error and lowest simulation time comparing with other TSM methods. Verification examples and comparisons are also implemented.","PeriodicalId":199234,"journal":{"name":"2017 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"2010 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127353186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The measurement is carried out in outdoorto-indoor (O2I) scene non-line of sight (NLoS). The frequency is 3.5 GHz and bandwidth is 100 MHz and 200 MHz respectively. Through the analysis of measurement data, two problems are explored in this parper. One is the method used to evaluate delay spread in such a large number of sub-channel system. Another is the effect of the transmission bandwidth and antenna number. The results reflect that array positions and measurement environments have various influences on delay spread. In addition, contrasting the results of different bandwidth, it clearly indicates that the delay spread of 100 MHz is greater.","PeriodicalId":199234,"journal":{"name":"2017 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127766932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
